I replaced condensor , evap, condensor and dryer today. Flushed lines, did not replace O tube. Pulled a vac and added a can of 134. Low side was 25 and high was 175, started on second can when pressure went too high. Recovered until low was 40 and high was 250. Inside air is not blowing cold, a/C line after O tube line is cool to touch and has some condensation and line before O tube is hot to touch. Not sure where to go with this?

High pressure generally indicates a blockage or clog in the system. Most likely the orifice tube you did not replace is clogged. The orifice tube is one of the first things that should be replaced when the air conditioning system is opened.
